String alignment in Java

How to output aligned strings?

Java provides a variety of methods to output aligned strings, including:

Using format specifiers

Format specifiers Can be used to specify the alignment of a string. The format specifier consists of the following parts:

• Alignment flags: Indicates the alignment of the string (left, right, or center).
• Padding characters: is used to fill unused spaces.
• Field width: Specifies the minimum width of the string.

For example, the following code right-aligns the string "Hello" and fills the gaps:

<code class="java">System.out.printf("%10s", "Hello");</code>

Use the String.format() method

String.format() The method can also be used to align strings. It uses a similar syntax to the format specifier:

<code class="java">String formattedString = String.format("%10s", "Hello");</code>

Using the StringUtils library (Apache Commons Lang)

The Apache Commons Lang library provides a StringUtils Class containing many utility methods for string manipulation, including alignment methods.

For example, the following code center-aligns the string "Hello":

<code class="java">String centeredString = StringUtils.center("Hello", 10);</code>
